Oil stains and attachments can seriously affect the anti-blocking and cutting strength of the disc. If the polished surface is not cleaned, the oil will cause the grinding head to slip during the grinding process, affecting the cutting force and prolonging the working time. The mixture of dust and oil will directly stick to the sand surface, which is not easy to shake off, causing the sand surface to block and reduce the cutting force.

The correct way: use a special degreaser, detergent, thoroughly clean the surface of the car body and then grind.

2, use P80-P240 sandpaper to polish as needed

The finer grain size sandpaper is mainly used for grinding the old lacquer film mouth of the putty, and is not suitable for the grinding of the atomic ash, otherwise it is very easy to block.

Correct practice: If the area of the putty is polished, use P80-P240 sandpaper as needed to achieve the grinding effect quickly.

3, cushioning pad to increase softness

The grinding head and the sand surface are both horizontal, and the body has some curvature in many details. The cushion is not used, and the grinding head is hard. During the grinding process, the sand surface and the grinding surface cannot be completely fitted or even partially separated. Not grinding. This will require repeated grinding to increase the amount of sandpaper consumed.

Correct practice: Adding XYS cushioning pad between the sandpaper and the grinding head can effectively increase the softness of the grinding head. When the curvature and the curved surface are used, the sand surface and the grinding surface can be better fitted, and the grinding effect can be achieved once, saving man-hours and sandpaper.

4, sand disc can be reused

Sandpaper is an industrial consumable, but not a disposable. Its role is to grind, so as long as the sand surface is not severely clogged, there is still a strong cutting force, and after grinding a surface, it can continue to grind one side. It is necessary to remind the operators and management personnel to avoid human waste from the perspective of environmental protection, and replace the new sandpaper after the sandpaper cannot be effectively ground.
